1 Claim.

This invention relates to a fluid discharge device for fluid containers, and in particular to an improved fluid discharge device of the type having an air vent .which insures a steady flow of fluid from the container by permitting the passage of air into the container to displace fluid discharged therefrom.

It is an object of the present invention to provide a fluid discharge device which will flt properly in the container opening and allow the fluid to be poured smoothly, without gurgling, bubbling, or the like.

Another object is to provide a fluid discharge device which will catch and retain fluid remaining on the pouring spout when the container is returned to a normal uprightposition after pourmg. l

A further object of the present invention is to provide a fluid discharge device which is simple in design and construction, and inexpensive to manufacture, and one which may be molded from a plastic or resilient substance.

Other objects and advantages will be apparent from the following detailed description accompanied by the drawing, in which: Figure 1 is a side elevational view of thedevice;

Fig. 2 is a sectional view taken longitudinally through the device enlarged with respect to Fig.

39 1, and illustrating the device as disposed in a container;

Fig. 3 is a sectional view taken substantially on line 3-3 of Fig. 2 and enlarged with respect thereto;

5 Fig. d is an enlarged sectional view taken substantially on the line 4-4 of Fig. 2; and

Fig. 5 is an enlarged sectional view showing details of the pouring lip.

Referring to the accompanying drawing, in

which like parts throughout the several views are indicated by the samenumerals of reference, it may be seen that a fluid discharge device embodying the present invention briefly comprises an annular closure or stopper portion I, surmounted by a tapered pouring spout 2 having an annular collar 3 which seats against the end of the neck of a container 4. A fluid duct 5 extends continuously through the device and is provided, intermediate the stopper and spout portions, with a web 6 which retains one end of a tubular, L-shaped air vent l.

The annular stopper portion I may be slightly tapered so that it will fit snugly in the neck of the container 4 and not fall out during pouring.

To enable the user to pour from the container without tilting the container so far, and also to insure that the web 6 and air vent l are uppermost during pouring, the axis of the tapered, conical spout 2- is disposed at an angle with the axis of the stopper portion I. Since it is natural to pour in the direction in which the spout is inclined, it may be seen that the vent i will be kept uppermost during pouring. As seen in Figs. 2 and 5, the fluid duct 5 is preferably provided with a flared pouring lip 8 at the free end m of the spout 2.

Beneath the lip d of the spout 2, a transverse slot or groove 9 is provided and extends for a distance equal to approximately one quarter of the circumference of the spout at this point. up The groove 9 is spaced a relatively short distance from the end of the spout and serves to help break the flow and catch and retain fluid remaining on the pouring lip 8 after pouring, and

in this way prevent dripping of fluid from the pp spout.

The vent l is provided to permit a relatively free flow of air into the container to displace the volume of fluid being discharged from the container in a smooth stream when the con- 25 tainer is tilted. Accordingly, the vent l' has an upturned end it which extends into the container and terminates at an air space.

The device may be formed in any suitable manner, but is preferably molded from a plastic 30 composition, such as rubber, rubber composition, or other plastic material. It may be molded in a single piece, or the vent may be separately formed and inserted, but it is desirable that the device be somewhat resilient and not of a brittle as nature.

It has been found that a device embodying the present invention may be readily and inexpensively manufactured and is advantageous for pouring fluids of all kinds, such as, for example, 40 inks, acids, etc.

It is to be understood that variations and modifications of the specific device herein shown and described for purposes of illustration may be made without departing from the spirit of my 5 invention.

What I claim is:

A resilient fluid discharge device comprising a closure portion for insertion into the mouth of a container, 9. fluid duct therethrough, a pouring 50 spout mounted on said closure portion and having its axis at an angle with the axis of the closure portion, an opening through said spout to permit the passage of fluid and air therethrough in opposite directions, an apertured web carried by said device and disposed intermediate the spout and closure portion and having a fluid duct in register with the fluid ducts of the spout and closure portion, a, tubular vent having one end secured in the aperture of the web and extending through and protruding from the closure portion, said vent being out of contact with the walls of the closure portion, a pouring lip disposed at the discharge end 0! said spout. and a transverse groove disposed below and adjacent the pouring lip, said groove being of appreciably greater extent in a circumferential direction than in an axial direction whereby fluid remaining on the spout after pouring is caught and distributed therein.
